A try to compose something in Republican chess. Although there is a strong symmetry (not apparent in diagram), we have at least 2 echoed mates... Later I discovered much deeper possibilities of Republican chess for problems with model mates.

It is necessary to restrict bK and bM movement for mating by single white moose. All 5 moves are used to this keeping in mind white must always have the move...

Cycle of black moves with switchbacks in model mates. The first version of idea that subsequently transformed into very high placing of Karol Mlynka in 5th WCCT. This is my little contribution to 2nd place of Slovakia.

Task of 10 totally analogous Andernach-motivated solutions. With such a quantity every quality becomes boring, doesn't it? (Although here quality is not very best...)

Echo mates with locusts, rather strong white technical material.
